Fixed advanced DataSource Filters to use proper logic tokens

[dandrayan]

Filtering did not work properly with more complex filters because the logic token from the top level was always being used, ignoring any logic tokens at the child level. I added a page to the examples project to demonstrate these fixes.

Sorry for the large number of file changes, I couldn't get the model binder to work with MVC3 so I updated to MVC4 (and had to update lots of dependencies too because of it). The important changes are in the KendoGridRequest and FilterObject files.

Not a problem. I'm going to blindly merge this since you brought the project dependencies into the modern era. I'll add you to the project too since I do zero work with Kendo and MVC these days.

Thanks!

Hi @dandrayan. Can you please check if my updated fork https://github.com/StefH/KendoGridBinderEx does also have this issue?

@StefH Your project looks good. KendoGrid.cs line 231 and KendoGridEx.cs line 310 both use the correct LogicToken. Now that I know your project exists, I may use it instead since it has the grouping and aggregates fully fleshed out. Thank you both for the hard work put into these projects.
